What are you looking to do exactly?, if I may be so bold. For sure Tektronics is a good investment! Looks all digital. I'm jealous.. :cry:
Well, with my electronics development I am getting into the limits of my old Tektronix 531A... It's also not in a good shape anymore. The trigger mechanism isn't really working anymore, even on digital (TTL) signals, so I can only do time-based measurements. And the time base is not calibrated anymore anyway. Lastly it uses up a LOT of space in my room... [EDIT: not to forget the occasionally puff of smoke coming out of it - at least once so far that I know of...]
So far this hasn't stopped me from using it and getting at least some good qualitative results. But my new 65816 card has a 50MHz oscillator on it, and even though none of the signals actually runs at that speed, I just can't see that signal on my scope. And 10-12.5 MHz static RAM access speed isn't too far away here. And I am still looking forward to finally fix these longstanding problems that make my DRAM-based video card so delicate to handle (depending on chip speed, phase of the moon etc). But for this I also need a decent triggering mechanism.
And as I think of going even further not only with CPLD with FPGA based developments, I thought that it's now time for a new scope. And as I believe in good tools, as they just make your life so much easier, it has to be a good one :-)
